The Kamov Ka-27 (NATO reporting name 'Helix') is a military helicopter developed for the Soviet Navy, and as of 2024 is in service in various countries including Russia, Ukraine, Vietnam, China, South Korea, and India.

Series production started at Kumertau in July 1979, and the new helicopter officially entered service with the Soviet Navy in April 1981.

[1] The Ka-27PS search and rescue helicopter can carry 12 folding seats or four stretchers in its cabin, and is equipped with a 300 kg (660 lb) winch.

In 2006, Kamov won the tender for the supply of Ka-32A11BC firefighting helicopters, to replace Aérospatiale SA 330 Pumas.

[8] The Ka-32A11BC features a high power-to-weight ratio and ease of handling, owing to its coaxial rotor design.

The basis of the modernization of the Ka-27M is installed on the helicopter airborne radar with an active phased array antenna FH-A.

[11] Ka-32s are used for construction of transmission towers for overhead power lines, as it has somewhat higher lift capacity than the Vertol 107.

[13] In August 2013, a Kamov Ka-32, C-GKHL operating in Bella Coola, British Columbia, Canada, experienced failure of one of its Klimov TV3-117BMA engines (manufactured by Motor Sich in Ukraine).
